Patented April 3, 1906.

Application filed October 27, 1905- Serial No. 284;,816.

To all whom it may concern:

Be it known that l, Josnrn GAYNOR, a citiat New New York, have invented new and useful Improvements in Sound-Boxes for Talking- Machines, of which the following is a speci'hcation.

This invention relates to an improved sound-box for talkin -machines of the class having disk shape records. With these machines it is necessary to frequently replace the needle enga ing the record.

The object 0 the invention is to provide means whereby the exchange of a new needle for the wornneedle may be quickly effected .n a simple manner and by a single manipulation.

In the accompanying drawings, Figure 1 is dleeeder Figfi, an enlarged section thereof 7 on line 8 8, g. 2; Fig. 9, a cross-section through the magazine on line 9 9, Fig. 1;

The letter 0. indicates the'sound-box of a talking-machine, to which is secured by a plate a the needle-holder b. The latter consists of a block having a perforation b, which extends from top to bottom and is ada ted for the reception of a needle 0. The per oration I) is of elongated or oval form, as shown in lFi 2. The needle 0 is normally containe within the inner portion of perforation I) and is sup orted upon a base-plate d, d of less diameter than the maximum diameter of the needle. The plate (1 extends below the inner portion of perforation b, but not below the outer por tion thereof. By means of plate (1 the needle is normally suspended from the holder in such a manner that its point (projects below the'same to engagethe recor The needle is secured in position by a clamp-screw e, tapped into the holder and bearing with its end against the body of the needle. Screw c has a toothed head or pinion e, engaged by a rack f integral with a plun or f, carrying a ush-buttonj' and retracts by a spring f he plun er slides in guides b of holder b, and by a vancing, the plunger screw e will be To plungerf is secured a laterally-extending resilient linger g, arranged in the path-of the tail h of an ejector adapted to throw the needle c laterally out of inner part of open- 7 ing 1) and into the outer part thereof as soon as the needle is released. The ejector is composed of an upper arm h and a lower arm 71 integral with an upright connectingspindie 7L turning in holder l) and influenced by a coiled spring h. The arms h W are arranged, respectively, opposite the upper and lower ends of needle 0, so that when turned they will throw the needle off support if! and out of inner part of o ening b. The movement of the ejector is effected by the advance of plunger f, which after slacking screw 6 will by finger 9' push against tail it, so that the arms h k are swung against needle 0. As soon as the finger g has cleared tail h the ejector is returned to its normal position by spring h.

The plunger f, besides expelling the worn needle in the manner described, also actuates the means for feeding a new needle and clamping the same to the holder. These means consist of a tubular casin i, secured to sound box a by bracket 11. Within casing i turns a cylindrical plug or needle-feeder 9', having a series of arallel and equally-spaced grooves j, each aflapted for the receptlon of one of the needles 0. The plug 7' receives in termittent rotatory movement from plunger 7 by two-arm lever la, fulcrumed to casing t at The forked lower arm of lever 7c grasps plunger f between a pair of collars f 4 f To the upper arm of lever is is pivoted a springpawl 1c, engaging a ratchet-wheel j fast on shaft 7' of p111 j. The ratchet-wheel 9' is further engaged by a detent l, that holds plug 7' against backward rotation.

The plug 7' is charged, preferably, from a number of magazines 'm, Fig. 8, o ening through casing i, to which they are etachably secured. These magazines are arranged side by side and will be successivel emptied by the intermittent rotation of p ug 7'. In cross-section each magazine m tapers to conform to the shape of the needle, Fig. 9. At its bottom casing 71 communicates with a chute n, having a curved or tapering side a and arranged vertically above the inner contracted portion of opening l). The tapering no side 71. of chute n serves to right the needles 0 after the latter leave plug j, as indicated in Fig. 7.

" Y A beveled spring-pawl 0, extendin across opening I), serves to prevent the nee le from falling out of the inner part of the opening before it becomes en a ed by screw e.

The operation 0 t e device will be readily understood. A pressure on button f wil cause plunger to advance and to perform during such a vance three successive operations. First, it will, by rack f and pinion e, turn screw 0 to release the worn needle 0,

which will then remain suspended on support (1. Second, it will, by finger g and tail it turn theejector to throw the released needle lateruntil it becomes seated on support (1. Upon the release of the plunger the latter is retracted by spring f During its return movement the plunger will by rack f tighten screw e a ainst the newly-introduced needle,

so that t e latter is clamped to the holder read for use.

at I claim is 1. A sound-box for talking-machines provided with a needle-holder, means for clamping the needle to the holder, and means for displacing the needle laterally from within the holder, substantially as specified.

2. A sound-box for talkin -maohines pro- 40 vided with a needle-holder aving an elongated opening, means for clampin the neeleto the ho der, and means for 'splacing the needle laterally from Within the opening, substantially as specified.

3. A sound-box for talkin rnachines pro- 'vided'with a needle-holder aving an elon gated openin a screw for clampin the needle to the ho der, a spring-pawl a apted to extend across the opening, and means for displacing the needle laterally from within the opening, substantially as specified.

4. A sound-box for talking-machines provided with a needle-holder, a plunger, and separate means operatively connected to the plun er for clamping the needle to the holder 5 5 and lor displacing the needle laterally from within the holder, substantially as specified.

5. A sound-box for talking-machines provided with a-needle-holder, a plunger, a pivoted ejector having laterally-extending arms adapted to engage the needle, and means for operatively connecting the plunger to said ejector, substantially as specified.

6. A sound-box for talking-machines provided with a needle-holder, a plunger, a clamp-screw, a pivoted ejector having later ally-extending arms, and means for operatively connecting the plunger to the clampscrew and to the ejector,- substantially asspecified.

7. A sound-box for talking-machines provided with a tubular casing, an inclosed grooved plug, a plurality ofmagazines communicating with the casing, a needle-holder,

and a chute intermediate the casing and said holder, substantially as specified.
